Description
The bag filter is a versatile filtration system characterized by its innovative design, compact size, ease and flexibility of operation, energy efficiency, high performance, leak-tight construction, and wide range of applications.
The interior of the bag filter is supported by a metal mesh basket. The liquid enters through the inlet and flows out through the outlet after being filtered through the filter bag. Impurities are trapped in the filter bag, and after replacing the bag, the filter can be used in continuous operation.
The following types of bag filters are available: single-bag filter, multi-bag filter, swinging bag filter, high-precision bag filter, etc., with a filtration accuracy of 1–10 microns.

- Replacing the filter bag is quick and convenient, and the filter does not require cleaning, which saves time and labor;
- The filter bag can be reused after cleaning, which helps reduce costs;
- The filtration accuracy of the filter bag is constantly improving and reaches 0.5 microns;
- The filter bag has a low level of side leakage, which effectively ensures filtration quality;
- The bag filter withstands higher operating pressures, has low pressure drop, low operating costs, and provides significant energy savings;
- The bag filter has a wide range of applications, flexibility in use, and various installation methods. It can be moved using small carts.
Design and Operating Principle
The bag filter is a pressure-type filtration device that primarily consists of a filter housing, a filter housing cover, a stainless steel filter bag reinforcement mesh, and other main components. The filtrate enters the filter bag through the side inlet pipe of the filter housing. The filter bag itself is installed in a basket made of reinforcing mesh. High-quality filtrate is obtained when the liquid passes through the filter bag with the required degree of purification, while impurity particles are retained by the filter bag. Replacing the filter bag is very convenient. There is virtually no material loss during filtration.
